2025: Preventing bots from being advertised

Antifrod Yandex began to prevent screenings. advertizing to boats Yandex announced this on October 16, 2025.

Thanks to artificial intelligence technologies, the updated anti-fraud algorithm is able to identify users with suspicious activity and robots and block their transitions to advertiser sites. So, according to the results of the launch, the number of froda conversions decreased by 2 times, and froda applications became 3.5 times less. Advertisers still pay only for the real actions of real users.

We always pay great attention to protecting our advertisers and their budgets from scammers and fraud. We see that many advertisers have faced a flood of fake applications and actions on their sites. Therefore, we move away from the standard approach of filtering robotic activity in statistics and are actively developing blocking frodan site transitions. Thus, we want to minimize any interaction of fraudsters with the sites of our partners. Thanks to the use of technologies based on artificial intelligence, we learn how to predict the actions of a robot and stop attempts to go to the advertiser's website. In addition, we see a trend towards a decrease in froda clicks, including thanks to analysis at the moment of selecting ads for the user, "said Gleb Sarychev, head of Yandex Antifrod.

The updated Yandex antifrod identifies and blocks some of the scammers even before the ad is shown. So, if earlier the system filtered robotic clicks after going to the site, now it analyzes behavioral signals and prevents ads from being shown to bots and users with suspicious activity. Further, even if the fraudster remained unrecognized at an early stage, the anti-fraud will work at the moment of clicking on the ad and show such a user a captcha. A successful check opens access to the site - but the advertiser does not pay for such clicks and conversions. Frode conversions are also not involved in training the algorithm of the advertising system.
